FORM FOR WALL CONSTRUCTION.

Patented July 9,1918.

Application filed June 24, 1915. Serial No. 36,122.

To all whom it may concern:

Be it known that I, EDGAR A. STANLEY, a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Forms for Vall Construction, of which the following This invention relates in general to the sub ect of concrete structures, and more particularly to a novel and practlcal means for erecting walls and the like without the aid of external forms,

The common practice in building or erecting poured concrete walls involves he use of external wooden forms. This method is expensive, both in material and labor, and is also wasteful of material. As is well known, the wooden type of retaining structure for concrete is not only costly initially, but also after having served its purpose, since prac tically all of the material once used is usually damaged to such an extent in tearing the forms apart'that itcannot be used again. Furthermore, in cases where it is desirable to provide walls constructed by this method with an external surface coating, it is difiicult to make this coating securely adhere and unite with the main wall body; That is to say,.sincethe wall concrete must become set before the external forms can beremoved, the surface thereof becomes hardened to sucha degree that it is practically impervious and impenetrable, thus preventing a homogeneous union with the finishing plastic coating applied thereto.

Accordingly, the present invention primarily contemplates the erection of concrete walls by a means which entirely dispenses with external Wooden forms, thus obviating the many objectionable features incident to their employment, and entirely eliminating the expense thereof. 7

Another object of the invention is to provide a wall structure comprising a plastic Wall body formed and sustained by retaining means of a character which permits the outside surfaces of the concrete body to be exposed so that the external finishing surface-coating may be applied thereto before the same sets, thereby securing a homogenelty and adhesion that is otherwise impossible.

A further object of the invention is to provide a wall construction in which the elements for retaining the plastic concretemaric forms in such a manner that the same will act as clog-forms to confine the main body of concrete and define its character and shape, and which, after serving this purpose, will remain in position to give added strength and reinforcement to the entire wall structure.

A still further object is to utilize the combined retaining and reinforcing elements in combination with a removable and collapsible core. This feature of the invention is of much, practical importance, since it makes possible a maximum economy in both plastic material used and elements left in the wall, without sacrificing strength or rigidity. Aside from this economic aspect, the combination of the-fixed retaining elements and removable core as proposed, provides a hollow wall structure which is especially desirable since it provides heat and cold insulating airspace's, is a retardant to sounds, and provides convenient means for installing pipes, wires, and the like. v A general object, including all of the foregoing special objects, is to provide for the erection of walls on a large scale involving the particular features set forth with a minimum expenditure of time and labor. In this connection, the invention proposes to v utilize the. removable and collapsible core devices for supporting a trackway for a concrete distributing car or the like, thus facilitating the construction to a material deree. 7

With the above and other'objects in View which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed. 7

In the embodiment of the invention disclosed in the accompanying drawings,

In carrying out the present invention,

which proposes to eliminate the useof external forms and otherwise facilitate and improve the erection of Walls and the: like, it is intende'd'to employ open Work or skeletonlikeretaining elements, such as metalrate-it forms which may be of any suitable character-or'design. However, in all cases the retaining means or metal fabric is' utilized as a so-called' clog, mesh 7, that is it is used for restraining and holding the main body of concrete while at the same time permitting the latter to ooze or squeeze through the same to a sufiicient extent to form a plastic base upon which the external finishing material may be appliedbefore the hardening or setting. of the mass; In other Words, thespaced concrete" retaining elements 1 are preferably made of sheet metal and comprise an open mesh bodywhich becomes clogged When concrete is poured between the same, thus backing up and holding the body of concrete caged therebetween to permit the same to set and harden in the usual manner, as Well as admitting of the desirable finishing operation referred to. It Will of course, be understood that meshes of various size and design may be utilized,

7 the selection depending entirely upon. the

characterof the Work, but in the present instance,. for the purpose of illustration, 50

there is shown a conventional form of Wire fabric, which can be more clearly observed fromFi In order to set up and hold these concrete retaining elements, or clog, mesh forms 1, inproper spaced relation, the same are connected by means of anchoring. elements or" ties 2 with suitable supporting units preferably in the form of removable and collapsible core devices designated in their enchori-ng ties 2 may be, of any construction tirety by the reference letter C. These anadapted for the purpose, but preferably are embodied in the form illustrated in the drawings, which is practical and capable of producing the desired results. That is to say, each anchoring tie may comprise a body portion haying one end thereof slitted to provide oppositely disposedmesh i engaging fingers tand 5, adapted to be bent or deflected so as to respectively engage both sides of the clog mesh forms and thus securely hold the same. The opposite end of the anchoring tie may be provided with outturned bracing feet 6, and'an intermediate holding tongue 71 The said outturned bracing feet 6 of the tie preferably bear against the outer face of one of the side Wall members 8 of the collapsible core C,

.thus bracing the tie against a lateral swingng movemennwvlnlethe intermediate holding tongue 7 temporarily enters a holding slot S formed in the side Wall 8, and is bent into holding position to prevent the clog mesh from being pulled away from the with the clog mesh forms, While the holding tongue 7 has a temporary engagement with the side Wall ofthe collapsible eoredevice, as Will hereinafter more fully appear;

Referring more partieula'rly to the structural features "and characteristics of the collapsible and removable core device-s jO, it will be observed more" especially from Figs.

3 and 1 that each of the same; is of hollow elliptical form and essentially comprises the opposite side all members 8, and the movable end capsectionstl. For the purpose of connecting the overlapping side members 8 and the end members 9, andpermittingj their collapse, so that the entire device may be removed from the Wall after the concrete is 1 set,- there is provided a, plurality of collapsible clip devices 10. These collapsible; clip devices include telescoping members ll'a-nd 12 which: are; respectively carried-by the end caps 9 and side Wall members 8 and are-s0 designed that they provide. a; freeway portion 13 and a contracted "s icket portion 14:.

To further increaseith'e efijectiv'eness' of the connection between the relatively contractible and eXpansible members 8 .and Q, the

lattermembers 9 carry endgame-strips 15 which ,sl'i'dablyengag in the guidestraps .16 carried by-the members 8, as vv ili'te apparent froinan inspection of Figs. 3 and l.

For the purpose of effecting thc' relative movements of the members Sand 9;to collapse the core device, and to also expand the I same to its normal position, there is pro vided an mte'nor operating" mechanism designatedi generally as .M. This mechanism essentially includes the crossed contracting levers 17 which have pivotally connected to their outer ends as at 18, adraw bar member 19, adapted to move within the limits of the collapsible clip member 10. Normally, that is when the collapsible core device is in its expanded position, these crossed contracting levers 17 assume the position shown in Fig. 3, and are held in this position by means of an expanding toggle 20, connected as at 21 with a toggle operating link 22 which is pivoted as at 23 to an actuating lever 24. In connection with the normal position of these parts, it will be observed from Fig. 3 that the draw bar members 19 are within the freeway portions 13 of the collapsible clip devices 10, thus pressing against the side wall members 8 and holding the same in their normal expanded positions.

With further reference to the actuating lever 24 which has a hand grip 25, and is pivoted as at 26, it will be observed that the same has attached thereto, the oppositely disposed end cap controlling links 27 which connect at their outer ends with the eyes 28 carried by the center of the end cap sections. Thus, when the actuating lever 2 is disposed transversely of the entire core device, the links 27 are forced outwardly to their limit, to hold the end sections in proper position. Accordingly, when the main actuating .lever 24 occupies this transverse position as shown in Fig. 3, it will be apparent that the contracting levers 17 are in their normal position. However. when this lever 24 is moved as shown in Fig. i, the toggleoperating link 22 will break the toggle joint 20, thus drawing the contracting levers 17 together and causing the draw bars 19 to travel from the freeway portion 13 into position to slide into the contracted socket portion 14eof the clips when the links 27 draw the end sections together. Therefore, the actuation of the lever 24 not only draws the end caps 9 together to collapse the core, but also releases the pressure on the side members 8 and draws the same inward a suflicient distance to become stripped or released from the concrete. It is obvious that the outline of the core may be varied by adjusting the outer or sliding members of the contracting levers or arms 17.

Before the collapsible core device can be withdrawn from the concrete wall, it will of course be understood that the temporary connection between the anchorin ties 2 and the side wall members 8 must e severed. That is, when the entire structure is set up as previously described, and the collapsible core is in its normal expanded position, and the holding tongues 7 will be exposed within the interior of the core, and in order to release the same from their engagement there- I with, it is proposed to utilize a gang chisel or other-suitable means to sever all of the holding tongues 7 from the body of the clip, thus releasing the cores from all holding engagement with any of the anchor ties and permitting their ready removal.

With further reference to the structural features of the collapsible core device C, it will be apparent from Figs. 1 and 2, illustrating the application thereof, that any necessary number of the same may be employed-and they are supplied with a cover plate 29 when in their normal position, thus effectually housing all of the collapsing mechanism within the core and preventing concrete from being spilled thereon. This cover plate 29 is preferably provided on opposite'sides thereof with rail supporting sections 30 into which rails 31 may be placed, which serve as a track-way for distributing cars, and also as an effective means of alining the different core sections, as clearly shown in Fig. 1. It will therefore appear that a concrete car or other concrete conveying receptacle may be wheeled along the trackway T and the contents discharged at any suitable or desired place between the concrete retaining members 1.

Referring generally to the features involved in the set-up of the present invention, it will be apparent from the foregoing description, that the spaced concrete retain- 'ing or clog mesh members 1 are. held in position by the anchoring ties 2 being temporarily connected by the tongues 7 with the hollow removable core devices C. These removable core devices are arranged in succession between the spaced metal fabric structures, in their normal expanded condition, with the cover plates 29 in place and the trackway T also laid. The concrete conveying vehicle may then be moved along the trackway and its contents discharged into the space between the concrete retaining members 1, thus covering up the anchoring ties 2 and backing up within the limits of the said members 1, in such a manner that the concrete oozes out of the mesh to a certain extent, although the main body thereof is confined. Before this main body of concrete, having portions of its surface exposed through the 010 mesh, is permitted to set, it is proposed do apply a surface coating 32 which entirely conceals the metal fabric form, and sets or hardens along with the main body of concrete, thus forming a homogeneous external coating and wall body.

After the wall body and external surface coating 32 has set or hardened to the desired degree, and the collapsible core devices or units C are to be removed, it is necessary to sever the temporary holding tongues 7 of the anchoring ties 2 as previously indicated, thus freeing the core from any positive connection with the concrete wall structure. The core unit's C may then he collapsed or contracted as previously described and Bodily removed from the Wall, leaving concrete, being left therein for reinforcing purposes as will be readily apparent.

While the foregoing sets forth a referred and practical embodiment of the intention, it'will of course be understood that various changes in the form, proportion and minor details of construction may be resorted to Without departing from the spirit of the invention or scope of the appended I I claim: e

1. A Wall formii'ig construction comprising spaced concrete retaining elements formmg permanent parts of the completed wall, temporary c'ore units arranged betwe'en said permanent elements, and ties having a releasable connection with the core units and a permanent locked connection with said permanent elements to also form parts of the completed Wall;
